Answer:
Principles of Geology
Explanation:
J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.
Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.
In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.
Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.

A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".
<u>Option: C</u>
<u>Explanation:</u>
Unlike constant reinforcement, partial reinforcement is only strengthened during certain times or time ratios, rather than emphasizing the action every single time. This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time. Thus here a batsman donot plan intentionally to make a century in every cricket match, but it goes random. Although when they need to score high on pressure, they force themselves to stretch as much possible which is not general.
Rabbits tend to wander a lot and if it runs into weed or grass... well it eats it. eating weed or grass allows rabbits to gain more energy. if the supplies of grass and or weed increases the population of rabbits would increase too. the more they eat the more energy the have and the more energy the have the more they reproduce.
more power = more reproduction
more reproduction = increase in population
so all in all the more weed, the better it is for rabbits since the amount of food increases
